Silence of the Night Colored

Work isn't that ambitious at the moment, so I finished the picture I began at the holidays.
And it's an colored sketch again.
I made the background on my own, a nice practice.
His claws remind me of Diablo *lol* Could it be because of the colors?
I say it again for all those who didn't look at the sketch of that picture: I got the idea for the sketch while listening to the song "Stille der Nacht" from ASP.
